Results from this study3

No result from this study comes from a test of the peptide.

Natural levels measured3

These results measure the body's own peptide. Nobody was given the peptide. They are not evidence about taking it. They are left out of key results, evidence counts and charts.

    In salmon brain, the body's own VIP was highest in the hypothalamus (112 pg/mg protein), followed by the telencephalon, olfactory bulb and optic tectum.

    In plain wordsIn salmon, the body's own VIP was highest in the hypothalamus, then the telencephalon, olfactory bulb and optic tectum.

    Summary
    Highest VIP levels were measured in the salmon brain with a maximum of 112 pg/mg protein in the hypothalamus, followed by the telencephalon, olfactory bulb and optic tectum.

    Summary · context
    The content of vasoactive intestinal peptide (VIP) was determined by radioimmunoassay in different brain regions of three fish species, namely salmon, trout and carp.

    This result measures the body's own Vasoactive intestinal peptide (VIP, aviptadil). Nobody was given the peptide. It is not evidence about taking it.

    In trout brain, the body's own VIP was highest in the olfactory bulb (111 pg/mg protein), with lower levels in the hypothalamus, telencephalon and cerebellum.
